Relaxation Effects in Small Critical Nozzles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We computed the flow of four gases (He, N2, CO2, and SF6) through a critical flow venturi (CFV) by augmenting traditional computational fluid dynamics (CFD) with a rate equation that accounts ...
Volumetric Gas Flow Standard With Uncertainty of 0.02% to 0.05%
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new pressure, volume, temperature, and time (PVTt) primary gas flow standard for calibrating flowmeters has an expanded uncertainty (k=2) of between 0.02% and 0.05%. The standard diverts a ...
